Customs Help with parts

Does anyone know what these 2 parts are for? One is a fender skirt that claims it’s for a 59 impala but after research haven’t found anything similar. I also have this bumper corner piece here that I’m also not sure what it goes to. These parts came with a bunch of classic Chevrolet parts and theses 2 I can’t find. Any help would be appreciated.

 

I think this may be your bumper extension.

 

I think it’s 69 impala not 59

 

Thank you guys, I was really struggling with these two!
